Nepenthes ampullaria, commonly known as the ampullaria pitcher plant, is one of the species in the Nepenthes genus with distinctive characteristics compared to other pitcher plants. The plant features small, round, pot-shaped pitchers, usually measuring about 5–10 cm in size. Their colours vary, ranging from light green with reddish speckles to solid green. Unlike most other species, the mouth of the ampullaria pitcher is wide and lacks a prominent peristome (the rim around the pitcher opening). These pitchers are often found growing directly on the forest floor in dense clusters.
